Hi svidal , can you try running qpress directly against the *.qp files, then run xtrabackup without --decompress option? Looks to me like you have potentially corrupted compressed files (qpress: Unexpected end of source file). Check the command line options as you might need to attempt recovery: [url] [/url]
Hi Coburn, sorry about last thaaaat much. Yes, at that time, I have ran qpress over all files. But thats does not matter, recently I could retrieve successfully a mysql database from one month back. I have to say this is a outstanding tool. Best regards!
I am migrating our CentOS 5.7 to Ubuntu 5.7. In Centos, we are using qpress with our xtrabackup. I installed percona-xtrabackup-24_2.4.28-1.focal_amd64.deb on our Ubuntu Focal. Do I need qpress? If so, where can I get it?
To save storage space, TDSQL-C for MySQL data and binlog backup files will be compressed with qpress and then packed with xbstream offered by Percona. Therefore, downloaded backup files can be imported to the target database only after being unpacked and decompressed.
If an error is displayed during the wget download, you can click here to download qpress locally and upload it to the Linux CVM instance. For more information, see Uploading Files from Linux or MacOS to Linux CVM via SCP.

A portable file archiver using QuickLZ
qpress is a portable file archiver using QuickLZ and designed to utilize fast
storage systems to their max. It's often faster than file copy because the
destination is smaller than the source. A few features:
multiple cores, reaching upto 1.1 Gbyte/s in-memory compression
on a quad core i7
64-bit file sizes and tested with terabyte sized archives containing
millions of files and directories
pipes and redirection and *nix-like behaviour for scripting and flexibility
Adler32 checksums to ensure that decompressed data has not been corrupted
data recovery of damaged archives with 64 Kbyte grannularity
unbuffered disk I/O (Windows only) to prevent disk cache of other
applications from being flushed
If you installed qpress from a Linux repo, as far as I can tell, these are still using the original unpatched 2010 source. You should replace your executable with a freshly built binary which includes the patch.
Percona XtraDB Cluster (PXC) offers a great deal of flexibility when it comes to the state transfer (SST) options (used when a new node is automatically provisioned with data). For many environments, on-the-fly compression capability gives great benefits of saving network bandwidth during the process of sending sometimes terabytes of data. The usual choice for compression here is a built-in Percona XtraBackup compress option (using qpress internally), or options compressor/decompressor for the compression tool of choice. In the second case, the popular option is the gzip or its multi-threaded version pigz, which offers a better compression rate than qpress.
One thing that needs clarification is the difference between the two methods using qpress (quicklz) compression. When using the compress option for Percona XtraBackup, the tool first compresses each file and sends it with .qp suffix to the joiner. Then, the joiner has to decompress those files before it can prepare the backup. Therefore, it is always a more expensive one as requires more disk space during the process.
